More than 1,000 people took to the streets of Guadalajara to mark four months since the forced disappearance of least 43 student protestors in the town of Iguala, Guerrero state. Demonstrators took up the familiar cry of “They took them alive! We want them back alive!” as they marched down Avenida Juarez on Monday, January 26.

At least 12 other countries had similar protests.

President Enrique Peña Nieto urged citizens to look to the future.

“I am convinced that this moment in Mexico’s history of sorrow, tragedy, and pain, should not leave us trapped. We cannot stay there,” Peña Nieto said.
